The left is criticizing Republican lawmakers for politicizing the hearing.

The right is criticizing both Strzok and House Democrats’ support for him.

“No matter how many times Strzok insisted that his professional actions were not impacted by his negative feelings toward Trump—and that agents are trained to leave their political beliefs at the door—Republicans insisted, without providing evidence, that his work had been tainted… [the hearing] reflected how far the Republican-controlled panels have been willing to go to discredit the probe into potential collusion between Trump’s campaign and Russia.”

“They want us to believe there was an FBI conspiracy to prevent Trump from being elected president, and what did that conspiracy do? First, it mounted a cautious investigation of what nearly everyone now acknowledges was a comprehensive effort by Russia to help Trump get elected, an effort that people on the Trump campaign and even in Trump’s own family tried to cooperate with. But then it kept that investigation completely secret from the public, lest news of it affect the outcome of the [election] in any way.”

“All of it, just like most of the broader House investigation, was a distraction from this central point about the conspiracy narratives the president and his defenders have been cooking up about the FBI: If the agency had been trying to harm Mr. Trump’s campaign, agents could have released damaging information on pro-Trump Russian interference before Election Day — and they did not.”

The right is criticizing both Strzok and House Democrats’ support for him.

Strzok “concluded a long oration on his own behalf by stating that the accusation that his anti-Trumpism affected his professional conduct ‘deeply corrodes what the FBI is in American society, the effectiveness of their mission, and it is deeply destructive.’... But most organizations have bad apples. Their misconduct is corrosive. Holding them accountable is not; it’s restorative. That’s why the FBI recently escorted Strzok out of its building.”

Regarding Strzok’s ‘we will stop it’ message, “the real question is what Strzok meant by the text. Strzok first said he didn’t mean that he had affected the investigation, then said he didn’t remember sending the text, after explaining he sent it late at night. None of this is credible.”

Moreover, “from the outset, it was clear that Democrats had no intention of gathering information — or doing their jobs, namely to conduct legislative oversight over the FBI. Instead, they turned the hearing into a partisan show of political grandstanding and feigned outrage.”
